From 7d616e4ddb9c0754ed6245a43332d5b867e4db11 Mon Sep 17 00:00:00 2001 From: Yury Norov Date: Tue, 5 May 2015 16:23:33 -0700 Subject: lib: delete lib/find_last_bit.c The file lib/find_last_bit.c was no longer used and supposed to be deleted by commit 8f6f19dd51 ("lib: move find_last_bit to lib/find_next_bit.c") but that delete didn't happen. This gets rid of it.
